I got sick of Google giving me a link to a PDF file and adding all their tracking crap to the URL so, I threw this together to get just the URL to the PDF. Basically, you put in an URL or a broken URL with hex characters in it (for example: %2F) and it either gives you the repaired URL or a list of arguments to choose from. Clicking "Guesstimate" will cycle through arguments that contain an URL. The cleaned up URL appears in the bottom text box. Requires .NET Framework 4.0 Client Profile or better.
